org.openqa.selenium.SessionNotCreatedException：会话未创建断开连接：无法使用 ChromeDriver 和 Chrome 将消息发送到渲染器错误

Question

I try to run this simple program on Java with Selenium:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;


public class MySelenium {

    public static void main(String[] args) {
        System.out.println("First Selenium");
        System.setProperty("webdriver.chrome.driver", "C:\\automation\\drivers\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.seleniumhq.org/");
        driver.quit();              
    }
}

But on running shows the following error:

How can i fixed this error ?

Answer 1

This error message...

org.openqa.selenium.SessionNotCreatedException: session not created 
disconnected: unable to send message to renderer

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser ie Chrome Browser session.

I suspect your main issue is the incompatibility between the version of the binaries you are using.

As per the snapshot you have provided the following set of binaries you are using looks fine to me:

• JDK : 1.8.0_191
• Selenium : 3.14.0
• ChromeDriver : 2.43
• Chrome : 69.0

Analysis & Solution

• As per Unable to receive message from renderer error using chrome driver 2.27 another pottential reason can be presence of antivirus within your localhost which you need to disable .

• Ensure that /etc/hosts on your system contains the following entry:

   127.0.0.1 localhost.localdomain localhost #or 127.0.0.1 localhost loopback

• Keep Chrome version between Chrome v68-70 levels. ( as per ChromeDriver v2.43 release notes )

• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• ( WindowsOS only ) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite .
• ( LinuxOS only ) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite .
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client .
• Take a System Reboot .
• Execute your @Test .

tl;dr

As per ChromeDriver 2.34 doesn't wait until iframe content loads after switching into iframe this issue was also observed with ChromeDriver 2.38 and Chrome 67+ combo and was related to static iframes (part of the originally loaded DOM) which seem to work correctly even till Chrome 66 .

Answer 2

Try using JDK 1.8.0_181. I had the same issue after updating to JDK 1.8.0_191.
